Abstract

Wireless baseband processing, which is characterized by high computation complexity and high data throughput, is regarded as the most challenging issue for software radio (SR) systems. To relieve this implementation difficulty in SR systems, the multicore architecture is proposed. However, due to the lack of the universal parallel programming framework for SR systems, it is difficult to take full advantage of the multicore architecture. To fill this gap, in this paper, an efficient parallel SR framework is proposed under the Cell multicore architecture for WiMAX base station (BS). With the proposed framework, one Cell blade server (including two Cell processors) can support up to three sectors, and each sector can support 20Mbps data rate for both uplink and downlink. The system performance results verify the effectiveness of the proposed SR multicore framework.
